Preheat the oven to 450°F.
Add the almond flour, baking powder, baking soda, (optional) oat fiber and salt to a bowl and mix using a hand whisk or fork.
In another bowl, add the eggs, sweetener, sour cream and melted butter and mix until combined. Add the cheese into the wet ingredients and continue mixing.
Add the dry ingredients into the wet and mix.
Scoop the biscuit mix into silicone muffin pan liners (or spray a non-stick muffin pan with non-stick spray) and bake for 10 minutes.
Lower the temperature to 350°F and continue baking for another 5-7 minutes. Allow to cool slightly before cutting into and serving.
